Most people, for most of their day, are trying to get by. Every day is essentially a series of problems, some minor, some major, some requiring more thought than others. Some we care a lot about; some we wish we didn’t have to. Some are welcome; some we even bring on ourselves because we enjoy solving them; others are deeply unwelcome. Some we care about initially, but then find we no longer do; some we don’t care about to start with, but they become important to us over time.
